■ hard seal electric butterfly valve product features
1, three eccentric multi-level hard seal butterfly valve, the fluid resistance is small, the sealing surface by the impact of small, does not change the medium flow, no spoiler, pressure drop, opening and closing torque is small, suitable for a wide range of pressure temperature.
2, the use of three eccentric oblique cone seal, the use of butterfly plate swing contact seal, seal opening and closing without wear, close off with the more tight, more reliable sealing performance, open to ensure that the sealing surface completely out of contact to ensure that the sealing surface is not damaged.
3, when the valve is open, the butterfly plate and the valve seat in the closed moment of contact, the use of butterfly plate eccentric 1, eccentric 2 quickly from the valve seat, reducing the wear of the seal, friction torque, open flexible. Eccentric cone 3 so that the valve in the open or closed when the butterfly plate through the valve seat hole, to achieve contact seal. In addition, the radius of rotation of the conical disc is greater than the radius of rotation of the sealing sub-contact position. Therefore, the butterfly plate will become more tight when the valve is closed, and the self-locking can be realized.
4, the sealing surface selection D507Mo and cobalt-based carbide and other materials, with corrosion resistance, high temperature, long service life characteristics, to overcome the use of high temperature thermal expansion valve easy to leak shortcomings.
5, butterfly plate seal with soft and hard laminated metal sheet, it has a flexible seal and soft and hard multi-level seal compatible dual characteristics, both in the anti-corrosion, high temperature conditions, have a good seal.
6, with ZTD, ZTHQ series of electric actuators, AC220V or AC380V power supply can be switched control.
